Why there are so many things that is consider evil or Haram/illicit in Islam?

It is because these worldly things distract one from the straight path. For example, it would be my option either to memorize a hi hop song/rock song rather than memorize a sura from the Quran. Women are to supposed to keep their beauty only to their husbands not to other people.Why else do you think is so common nowadays. Drawing living breathing things is considered replicating God's creation and we shouldn't do it.
